RAILWAY SNOW-PLOW.

Specification of Letters Patent.

Patented Oct. 31, 1911.

Application filed April 6, 1910. Serial No. 553,793.

To all whom it may concern:

Be it known that I, ORVILLE O. MANN, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented new and useful Im provements in Railway Snow Plows, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

The purpose of this invention is to provide an improved construction of apparatus for cleaning snow from a railway road bed.

It consists in the elements and features of construction and their combinations shown and described as indicated in the claims.

In the drawings 2 Figure 1 is a plan view of a portion of a car equipped for embodying this invention. Fig. 2 is a side elevation of the end portion comprising the plow showing the same folded up out of operative position. Fig. 3 is a front end view of the device folded up as seen in Fig. 2. Fig. 4 is a side elevation of the structure shown in Fig. 1 with the plow in operative position. Fig. 5 is a detail section at the line 55 on Fig. &.

For this invention an ordinary flat car whose side sills are represented at X, is provided at one end,which in operation is the forward end,with an inclined support, 2, 3, the rear part 2, being fixedly mounted on the car, and the forward part being hinged to said part, 2, for folding up to upright position as seen in Fig. 2. On the forward part, 3, there is mounted a scraper or shovel member, 4, having its forward lower edge extending transversely of the car, and its surface inclined back therefrom corresponding to the slope of the inclined support, being preferably at an angle between 30 and 45 from horizontal. Upon this inclined track there is mounted for sliding up and down, the main head, 5, of a snow plow, comprising two transversely concave deflecting wings,diverging rearwardly from their junction at the forward point of the plow head, suitably supported and braced, the support consisting of a metal covered plank, 6, strengthened by longitudinally extending angle irons, 88, positioned for extending between and respectively close alongside the fore-andaft inclined angle iron side bars, 77 of the fixed upper part of the inclined support, 2. At the operative position of the plow head it is secured to the bars, 7, by removable bolts, 7 taking through the plank, 6, and the horizontal flanges of said angle iron side bars. For further guidance, but more especially for locking the sliding plow head down onto the support throughout its sliding movement thereon, retaining plates, 8 are bolted onto the under side of the plank 6, and offset from the lower face of the plank at their inner marginal portions, so as to engage under the horizontal flanges of the angle iron side bars, 7. (See Fig. 5.)

The nose piece or prow, 9, of the plow is mounted fixedly upon the forward hinged member, 3, of the support, and is constructed for lapping at its rear end over the lower forward end of the head, 5 (as seen in Fig. 4:), said lapping portion of the nose and a corresponding point in the plow head, having apertures for a bolt, 10, by which the nose piece is secured to the head at operative position. For sliding the head up and down on the support, a cable, 11, is connected to said head at the lower side of its upper end, the connection being most conveniently made as illustrated, by providing an eye bolt, 12,

projecting up from the metal-armored plank, 6, as seen in Fig. 1. The cable 11, extends up over a guide pulley, 13, and thence down about a guide pulley, 14, and is made fast to the stems 15, of a piston, not shown, traveling in the horizontal cylinder, 16, so that the retraction of the piston in the cylinder which may be caused by the admission of a motive fluid, as compressed air, to the forward end of the cylinder through the pipe, 16*, drawing on the cable, pulls the head, 5, up along the inclined support, the bolt, 10, having been first removed to disengage the head from the nose, 9. When the head has been thus retracted to a position shown in Fig. 2, the forward member, 3, of the support is folded up by means of a cable, 11 attached at an eye, 17, at the middle point of the forward edge of said forward member, the cable passing up-about a guide pulley, 18, mounted upon the upper forward corner of the plow head, and thence about a pulley, 19, at the top of the support, and thence down around a pulley, 20, and thence rearward about a pulley, 21, on the forward end of the stem of the piston not shown, which plays in the cylinder, 22, the cable after passing about said pulley, 21, being made fast to the car at a point forward of said pulley,so that the retraction of the piston in the cylinder folds up the said for ward member.

hen folded up to the position shown in Fig. 2, the parts may be made secure in that position by a coupling rod, or hook 23, which may be engaged with an eye, 24, at the head of the support, and with the eye, 17, to which the cable, 11*, is attached. \Vhen the member, 3, is folded down to operative position, it is securely interlocked with the upper member, 2, and stopped at a position at which it constitutes a continuation in the same plane of the inclined slope of the upper member, this being effected by lower side bars, 25, 25, which are secured to and rendered rigid with the upper bars, 3, constituting said forward member of the support proper, being parallel and at a short distance below the same, so that in swinging downward to the operative po sition of the said lower member they project back under the lower end of the upper or fixed member of the inclined support, and stand alongside the longitudinal side beams of the car, X, to which they are bolted for holding the member 3 in said operative position. For further insuring the correct alinement of the two members of the support when in operative position, there is rigid with the car sills X, and with the bars, 7, at the lower end of the latter, a forwardly open transverse channel bar, 26; and the rear end of the member, 3, is provided, for rigidity and the specific purpose of cooperating with said channel bar, 26, with an angle bar, 27, whose flanges are respectively horizontal and vertical at the operative position of the member 3; the horizontal flange being positioned so that at said position it engages above said lower flange of the channel bar, 26, whereby said channel bar affords a positive support for the upper end of the hinge member and insures the alinement of the upper surfaces of the two members at operative position, and it will be noticed that when at this position, the head, 5, is moved down into engagement with the nose, 9, and the bolt, 10, is inserted connecting the head and nose, there is formed an effective lock against upward swinging of the forward member.

The snow plow as thus far described, it will be observed, is adapted to clean the snow from above the track down to a point as close as it is considered prudent or necessary, to mount the lower edge of the shovel member, l. For cleaning the snow from between the rails, and to deflect the snow oli' to the two sides there is mounted underneath the car back of the inclined support, 2, 3, a plow member consisting of two converging wings, 30, 30, mounted at their apex which is foremost, upon a vertical rod, 31, which is rigid with the car, having its lower end held in a bracket, 32, extending down from the car past said plow member, having a rigid vertical stem, 33, extending up through a guide bearing in the car base, and connected thereabove by a cable, 34:, to the piston, 35, playing in a vertical cylinder, 36, the cable intermediately passing over an elevated guide pulley, 37, so that the depression of the piston in the cylinder by pressure of the motive fluid admitted through the pipe, 38, draws upon the cable, 34, and lifts the plow. The lower edges of the two wings of the plow, 30, are notched at 30 for striding the rails so as to clean the snow off from the top of the rail and for a distance down at both sides of it.

It will be understood that an operator on the car can control all the movements of the device by operating the valves which control the air connections with. the several cylinders mentioned.
